Eosinophilic Folliculitis

Key points
Condition results in finding bumps or blisters around the hair follicles.
Cause is unknown, often comes as a result of immune deficiency.

Eosinophilic Folliculitis is also known as Eosinophilic Pustular Folliculitis or Ofuji Disease. The name is due to skin biopsy finding of eosinophils (a type of immune cell) around hair follicles. Eosinophilic Folliculitis is rare and more often affects males than females. The cause is not known. Eosinophilic Folliculitis is often a feature of immune deficiency.

Eosinophilic Folliculitis presents with red or skin-coloured dome shaped bumps and pus-filled blisters. It may look rather like acne or other forms of folliculitis. These mostly appear on the face, scalp, neck and trunk and may persist for weeks or months. Less commonly larger red irritable wheal-like patches may appear. Palms and soles may rarely develop similar bumps and blisters, but in such cases the condition should not be called folliculitis as there are no follicles in these areas.
